Activated Aluminas are synthetically produced amorphous oxides from aluminum trihydrate. The end product is a beaded material or powder with highly adsorptive capabilities. It is used as a Claus Catalyst in natural gas and refining and can reduce the dewpoint of the air to -40C. Special grades can reduce the dewpoint to less than -100C. With new technology, we can now remove a variety of contaminants from styrene, polyethylene, ethylene, light hydrocarbons and air. Aluminas are very nonreactive adsorbents giving off low heats of adsorption. Surface areas and surface areas can be controlled during manufacturing to allow for custom purification applications. Sepcor Aluminas include high surface area products for air drying, natural gas dehydration, liquified natural gas.  Proprietary aluminas for sulfur removal, HF alkylation, Air Prepurification, Hydrogen Peroxide Purification
